Nitrogen and phosphorus budget in rewetted fens

Water Science and Technology, 2001
A former dewatered fen was flooded for a multi-purpose landuse system including cattail production, fen protection, and water purification. These research plants with an area of 6 ha consist of three constructed surface-flow wetlands. The inflowing water is polluted by non-point sources due to intensive agriculture.

Delayed rainfall diminishes the positive response of soil respiration to warming

Grassland Research, EarlyView.
Warming stimulates soil respiration and its components, while delayed rainfall suppresses them. Crucially, delayed rainfall diminishes or even reverses the positive response of soil respiration to warming by intensifying the drought stress, and autotrophic respiration is more vulnerable than heterotrophic respiration under this interaction.

Water quality dynamics following re-wetting of agriculturally drained peatlands: A mesocosm experiment

Sustainable Environment
Peatland rewetting is an effective restoration strategy to reduce carbon losses, halt soil subsidence and restore ecosystem functioning. However, rewetting drained and degraded peatlands may release stored nutrients and potentially toxic elements into ...

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Nonisothermal Spreading Dynamics of Self-Rewetting Droplets [PDF]

Langmuir, 2018
We experimentally studied the spreading dynamics of binary alcohol mixtures (and pure liquids for reference) deposited on a heated substrate in a partially wetting situation under nonisothermal conditions. We show that the spreading mechanism of an evaporating droplet exhibits a power-law growth with early-stage exponents that depend strongly and ...

Food Security Versus Environmental Health: The Nitrogen Dilemma

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Nitrogen is an essential element for plant growth and, consequently, crop production. However, the cycling of nitrogen in the environment can have negative effects. Here, we review the historical development of scientific and public awareness of these effects and the influence this has had on political action to control them.

Short-Term Effects of Drying and Rewetting on CO2 and CH4 Emissions from High-Altitude Peatlands on the Tibetan Plateau

Atmosphere, 2016
This study used mesocosms to examine the effects of alternate drying and rewetting on CO2 and CH4 emissions from high-altitude peatlands on the Tibetan Plateau.

Effects of Crop Rotation and Hydrogel Application on Soil Biological Properties and Wheat Biomass Production in Drylands

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aim Conservation agriculture (CA) is rapidly gaining traction to promote sustainable crop production, focusing on minimum soil disturbance, permanent soil cover, and strategic crop rotation. Moreover, hydrogel is increasingly being used to improve water retention, including in combination with CA, particularly in water limited ...

Effect of Simulated Drying-Rewetting Cycles on Soil Respiration and Dissolved Organic Carbon and Nitrogen Stability in Zoige Alpine Wetlands

Shuitu baochi yanjiu, 2020
With the global climate change, extreme droughts and heavy precipitation events occur frequently, thus soils are undergoing more complicated and frequent drying-rewetting cycles, which have an important effect on soil respiration.

Soil Type Controls the Effects of the Nitrification Inhibitor DMPP on Nitrate Leaching and Mineral N Retention Under Simulated Heavy Rainfall

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Nitrate (NO3−) leaching is a major nitrogen (N) loss pathway in agriculture and may increase with more frequent heavy rainfall. Nitrification inhibitors, such as 3,4‐dimethylpyrazole phosphate (DMPP), can reduce these losses, but their effectiveness under frequent heavy rainfall events remains unclear, which limits their targeted ...
